Short summary
Tropical cyclones forming in the southwest Indian Ocean frequently affect mountainous island nations. However, their role in modulating rainfall has not yet been thoroughly investigated. Using both observational data and a high-resolution numerical model, we aim to improve our understanding of the orographic effects of Madagascar and Réunion Island on approaching tropical cyclone (TC) track, intensity, and, ultimately, heavy rainfall using a representative case: TC Batsirai (2022).
